Wiring procedure
1 <F1/F2> wiring between this equipment and centralized control equipment is required.
2
The connection to the facility equipment and setting of various switches are required.
See the “Wiring with Facility equipment” paragraph.
3
Connect the power supply and earth.
See the “Power Supply & Earth wiring” paragraph.
3 For the wiring connection and clamping method, refer to the “Wiring lead-in” paragraph.
Wiring with Facility Equipment
<Caution> The length of wiring between this equipment and facility equipment is 100m max.
Abormal input
When the contact is “Open” or “Closed”, “Error” is produced.
Input specifications: No-voltage “a” contact
(The welding current is approx. 10mA when the applied voltage
is 20 to 30 V DC and the contact is “Closed”.)
For input, use the contact to micro current. (12VDC, 1mA max.)

Power Supply & Earth Wiring
For power supply, 1~200-240V is used. The wiring to the power terminal
block (L/N) is required. The electric wire used should be 1.25 to 2.0mm2. After
checking the power supply specifications, make correct connections.
Connect the earth wiring to the “
” terminal. Use a 2.0 mm2 wire.
